Application Med April 25, 1921. Serial No. 484,078. y

To all whom 'it 'ma/y cm1/oem! Be it known that I, WILLIAM A. CAMP- BELL, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Vises, of which the following is a specification.

My invention relates' to improvements in vises.

An important object of the invention is to provide a vise having means whereby it may be rigidly locked upon a member secured to a work bench, and conveniently and quickly removed therefrom, without disturbing the work held thereby, and carried to a machine, for use in connection therewith.

A further object of the'invention is tol provide a plurality of interchangeable sets section through the same,

of jaws, for the vise, with means for detachably securing the same to the operating parts of the vise.

A further object of the invention is to provide a device of the above mentioned character, which is simple 'in construction, strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

ln the accompanying drawings forming a part of this speciication, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of a vise embodying my invention,

Fig. 2 is a central vertical longltudlnal Fig. 3' is an end elevation of the vise,

Fig. 4 isA a transverse section taken on line 4 4 of Fig. 2,

Fig. 5 is a plan view of a base,

Fig. 6 is a plan view of the stationary body of the vise,

Fig. 7 is a side elevation of a jaw, of a slightly dierent form, and,

Fig. 8 is a similar view of a still diierent form of jaw.

In the drawings, wherein for the purpose ci illustration is shown a preferred'embodiment of my invention, the numeral 10 designates a preferably flat base, provided near one end with an, opening 11, receiving a headed stud 12, this stud passinof through a portion of a work bench 13. he headed stud is provided with a head 14 and an enlarged portion 15 therebeneath, forming a shoulder 16, which engages the base 10, thus retaining the head 14.spaced from the base. The base 10 is further secured to the bench 13 by bolts 17, extending from the 4lower side of the base, and passing through the bench, and provided with nuts 18, as shown. At its opposite end, the base 10 has an angularly arranged tubular boss 19, internally screw threaded to receive a clamping screw 20, which is angularly arranged, and provided with an enlarged milled head 21, as shown.

The numeral 22 designates the stationary member of the vise, embodying a lower base portion 23 and a tubular guide or housing 24, referably cast integral therewith, and vertically arranged within this guide or housing is an upstanding lug or boss 25, preferably integraLwith the base portion 23, and provided with a screw threaded openin 26. v

t its forward end, the base portion 23 is provided with a notch or recess 27, adapted to engage beneath the head 14. and to receive the enlarged portion 15 of the headed stud 12, as clearly shown in Fig. 2. At its forward end, the base portion 23 has a lower angularly arranged recess 28, receiving the,

free end of the clamping screw 20,v which free end is without threads, as shown at 29. The edges of the base portion 23 slide within inverted L-'shaped guldes 30, secured to the base 10, by screws or bolts' 31. By virtue of the angular or inclined arrangement of the .clamping screw 20, the same functions to urge the base portion 23 longitudinal in a forward directlon, toclamp against the headed stud 12, and also to raise it vertically, to clamp beneath the inverted L- shaped guides 30, whereby the stationary member 22, is securel clamped against perceptible movement. v unscrewing the element 20, so that the end 29 thereof is withdrawn from the recess 28, the base portiony 23 may be readily moved Alongitudinally from` beneath the guides 30, as shown.

The numeral 32 designates the movable member of the vise, embodying a longitudinal tubular portion 33, having a longitudi nal slot 34 in its lower end, for the passage of the lug 25. The tubular portion 33, preferably square in cross section, slidably fits within the bore of the tubular guide or housing 24, Fig. 4i.

At its rear end the tubular portion 33 is provided with a head 35, having an opening 'longitudinally in either direction, as de` reception of anchor pins 45,

rparts 42 'and 43 therein for receiving a rotatable feed screw 36, a collar 37 being clamped thereon, upon one side ci the head, while a co-acting collar 38 is termed upon the eedscrew upon the exterior of the head 35. An apertured head 39 is formed integral with the collar 38, and carries a handle 40, to turn the same. rlhe iced screw '36 has a screw "threaded portion 4l, engaging in the screw threadedopening the lng 25., By turning the feed screw, it is obvious that the member 32 isi moved sired. a

The stationary member 22 embodies a jaw attaching part or shank 42, and the Inovable member 32 has a correspondingly arrahged jaw attaching part-- or shank 43,

which. are similar, and preferably formed integral with the members carrying the same; These jaw attaching parts have vertical preferably cylindrical openings 44, for the rigidly secured to a pair ci co-acting jaws 415. These ancher-,pins are provided with annular grooves 4'?, having lower walls-48, which are conical, increasing in diameter downwardly. The have transverse screw threaded openings 49 and 50 respectively,

vtfor receiving clamping screws or bolts 5l and 52 respectively, having milled heads 53. As is more clearly shown in Fig. 4, each ci these clamping screws has a tapered end 54, to engage with the conical wall 48, and by virtue of the conical wall 48, the action oi the clamping. screw is not only to hold the jaw against displacement, but to bind vit downwardly, tor er'iecting a rigid `connection. llachV jaw is preferably' provided with a depending lug 55, to engage the inner side of the part 42 or 43, `thus preventingrotation oi the jaw. ln Fi l, the jaws 46 are straight, or plain. ln ig., 7 the jaw7 is provided with a lil-shaped opening or` notch 56, while in Fig. 8 the jaw is provided'with lll-shaped rated. The jaw in Fig. 7 is designed to han- Ad'le round worlr ot various kinds, while the jaw in F ig. 8 may be emlployed for handlingpipes, rods or the like. will be understood notches 57 'and .58, which are ser-- accenna ofcourse that a pair of the jaws in Fig. 'l' are employed together, and the same is true with the jaw shown in'Fig. 8.

lt is to be understood that the forms ci my invention, herewithshownl and described, are to betalren as preferred examples of the same, and that various changes in the shape, size, and arrangement oi parts may be resorted to without departing from the spirit vits opposite end with a lower inclined recess to receive the upper end oi the inclined clamping screw, and-guide means carried by the base and engagmg over the edges oi said base portion. Y

2. a vise, a base provided near one end with a headedstnd extending above the same, said base' being provided near its opposite end and upon its lower side with an inclined boss having a screw-threaded opening, said screw-threaded opening being inclined and extending upwardly toward the heated' sind,

an inclined clamping screw engaging within the serew-threaded opening and havii'iij` its upper end adapted to project above said base, a' vise to be secured to said base, said visecomprising a base portion provided one end withl a notch to receive the headed stud and near its opposite end and in its lower side with an inclined recess'to receive thev upper end ot the inclined clamping screw, guides secured tothe base and extending over the base portion of lthe vise. y
